1. What is Total Interest Calculation?

Total interest calculation determines the total amount of interest paid over the life of a loan or debt. It helps borrowers understand the true cost of borrowing beyond just the principal amount.

The calculator uses the formula:

Where:

• \( EMI \) — Equated Monthly Installment (currency units)
• \( m \) — Number of months (unitless)
• \( P \) — Principal amount (currency units)

Explanation: This formula calculates the difference between the total amount paid and the original principal, giving you the total interest cost.

Details: Understanding total interest helps consumers make informed financial decisions, compare loan options, and plan their debt repayment strategies effectively.

4. Using the Calculator

Tips: Enter your monthly payment amount, the total number of months in your loan term, and the original principal amount. All values must be positive numbers.
